Abstract
An expandable osteosynthesis implant has branches ( ) each connected at one end to a seat ( ) which is pierced by an orifice ( ), suitable for being slid from a posterior direction between the facing faces of two consecutive vertebrae in order to hold them a given distance apart and restore stability of the spinal column. According to the invention, the branches ( ) and the seat ( ) define a hollow cage ( ) which, in a “rest” position, has an outside general shape that is a cylinder of circular section, and a portion at least of the inside volume ( ) of the cage ( ) towards the distal ends of the branches ( ) is in the form of a circular truncated cone whose large base is towards the seat ( ), which implant has at least three branches ( ) and, inside the inside volume ( ) at least one spacer ( ) suitable for passing through the orifice ( ) and the large base of the truncated cone.
